Slightly hunched forward, seemingly coming out of nowhere, the young woman wobbles towards him. Her gaze desperate, her hands flailing, she mutters something in a language he does not understand.

But before he can even take a guess at what she might want, she buckles over and sinks to her knees. Tears welling up in her dark eyes, perspiration is glistening on her forehead, she keeps stroking her protruding belly.

Suddenly he understands.

He pulls up his phone and calls for an ambulance. Her face relaxing, the woman is nodding her approval, before her grateful grimace vanishes in another contraction.
